Metallurgy
Compositional data of elemental metal and metal oxide percentages of any material culture objects, including metals, ores, slags, ceramics etc. Within the dicipline of compositional analysis there is little agreement on how to store meausrements below detection limit, some are pulished as zero, or NA, or NULL, BDL, or hyphen etc. Here we use NULL, which simply means below detection limits.
Column name	Data type	Column description
MetallurgyID	varchar	Starts with 'ME' specifying the unique row in this table.
MaterialCultureID	varchar	Starts with 'M' specifying the unique object that is stored in the MaterialCulture table. It is possible for multiple rows to belong to the same object.
Label	varchar	Analysis label provided in the primary literature. Crucial to be case sensitive, as literature do make a disctinction.
Sample	varchar	Slag sample number
LaboratoryMethod	varchar
Structure	varchar	Analysis is either a bulk sample at a broadscale across a large area, or at a fine scale on specific structures that are discrete micro- or nano- scale pockets (inclusions).
